Decisions, decisions!

My pair of Apple earbuds recently broke. Well, more specifically, one of the earbuds did. I can no longer hear anything out of my left earbud. VERY annoying!

Anyway, I figured it was time to upgrade. Based on the type of music to which I listen, I am hoping to find a set of earbuds that will give me a little less base and a little more treble (1/2 of my iPod is Broadway actually). I'd like to spend under $100, although will spend more to get what I want. My concern with the Klipsch S4 is that they're too bass-y

Any suggestions? I am new to the world of audiphilism, so guidance is necessary!
